Title covers it really. I'm not super experienced with film yet but this was a very fun roll to get back from the lab. It leans quite blue in daylight/white light of course but even then the colours are satisfying.

The halation/light burn you get from direct light or point light is very cool and, if you're chasing it, it fun and surreal.

It's a dreamy film! Can't wait to shoot more now that that I've experimented with a roll.

I would say that this film can shine in low light / night situations with a lot of the scene indirectly lit; the sample photos seem manipulated towards higher saturation; I enjoyed using it daytime indoors with available light only. ... If you can afford Portra 800 it would be a better choice for more natural colours and greater flexibility while Cinestill can bring out certain hues and higher contrast and can be manipulated but with less predictable results; never tried it daytime outdoors at 500 with a recommended filter but I reckon it would need a fair amount of practice to achieve pleasing results. I have seen a few great outdoor photos with interesting saturation (although not uniformly across the spectrum) but cannot think of using it that way regularly myself; if there is a good amount of both direct and indirect light it can perform outdoors ok but colours may be a little unpredictable; not what I would be willing to experiment with or aim for. Some might think it offers opportunities for creative portraits; arguably portra will give you a lot more natural skin colour. in any case most light sources will be easily blown (missing annihilation) and extended to unpleasant halos esp noticeable in very low light and highly contrasting scenes.
I have managed to get what I wanted during my visit of some Eastern European friends mainly with available light and with no harsh direct light sources; the colours are not quite there but some might enjoy the neutral render.

Caveat: I'm new to shooting film and I've heard a lot of hype around CineStill 800T so as a Christmas treat I bought two rolls and threw caution to the wind using my POS camera with it at box speed.

The way things turned out I ended up shooting it under quite varied lighting conditions and didn't necessarily give it the opportunity to play to it's strengths.

Despite this I was really happy with the results, there's definitely a blue cast indoors and in daylight as per the description but I actually really liked it. It gave some photos a slightly more dream like effect which I loved.

The halation was interesting and manifested in ways I didn't expect which I think added character to images but also was a little overpowering in some instances.

I also, shot a roll of Portra 800 at a similar time and I think that was a bit more forgiving and even. Whereas CineStill 800T was a bit quirkier and maybe a little more hit and miss. The Portra 800 had more hits but my favourite photo from the holidays was with CineStill 800T. A lot of the best pictures had friends and family so I won't upload them here but hopefully some of these give an indication of how it behaves.

I would definitely buy this again but potentially be a little more selective and maybe even shoot it with my newly acquired SLR for more control.

it was good surprisingly even in autumn cloudy daylight
a little bit sunnier and would be blurry probably

Cinestill 800T is my personal favourite film stock, it’s perfect for everything with its distinctive colour and results, and its beautiful look when used at night. I’ve used Cinestill in all environments on multiple subjects, during the day and at night, and always been pleased with the results I’ve ended up with.
Cinestill 800 is a stock you should try out no matter what you shoot, as it’s an incredible stock to use.
